I installed the same code on the main site and the subdomain, without any alterations on either. All pages, from both, are being tracked and display correctly in the reports. I have to set a goal with a funnel for the shop.example.com. Analytics, however, only lets me set the second part of the URL i.e. /thank.you without the shop.example.com or example.com.

My question is, will the goals and funnel steps be tracked correctly or do I still need to make some alterations to the code on shop.example.com? Thank you for your help! Magda

Answer: Hi Magda, in Universal Analytics you don't have to change the code to track users across sub-domains. If your Thank you page is a unique page across all subdomains your goal should work properly. If it's not, you need to create a filter showing the full URL:
